chines, of which the following is a specifica-- tion, reference beinghad to the accompanying drawings,.forming a part thereof.

My invention relates to typewriting machines and has special referenceto such as are adapted for use in making duplicate bills or the like inconnection with aseries of continuous webs or strips of paper which aresuperposed and have sheets of carbon paper, or other means for makingduplicate copies, between them.

One object of my invention is to provide a simple and durable machine bymeans of which duplicate bills or the like may be produced on acontinuous web and readily cut or torn off when the typewritten matteris completed, without tearing the carbon pa.- per or other means of likenature which is used for producing the duplicate copies, and whereby theduplicating sheets may be used repeatedly until they are worn out.

Another Objectis to provide a machine for the aforesaid purpose whichmay be readily adjusted to the length of the bills which are to be madeout on the machine, so that after the machine is set there will be noquestion but what the bills will be separated. from each other and fromthe web,l along the proper line of division between them.

Another object is to provide a mechanism which may be applied totypewriting machines of well known types without material change, or inother words, an attach ment whereby ordinary typewriters may readilyadapted for use with multiple 'sheet webs.v v

@ther cbiects and advantages of in4 vention will be set forth hereinafparticular fleld cf use;

lin the drawings,-10 designates the frame of a typewriter including abase 11, 12 designates the carriage, 13 the platen, and 14 the spindleto which the platen is secured.

The spindle 14 isrotatively mounted in suitable bearings 15 in thecarriage 12 and is provided at its respective ends with knobs 16 bywhich the platen may be readily turned. Mounted' on the spindle 14 closeto the platen is the usual spacing ratchet wheel 17. All of the partsyso far mentioned are arranged in a well known manner and perform theirusual functions.

Extending parallel to the platen is a cutting bar 19 arranged to cut theweb along the line of division between the bills. A frame 20 is attachedto the carriage 12 and extends backwardly from the typewriting machineas shown in Figs. l and 4. It is composed of side bars 21 supportingbrackets 22 and transverse rods 23-24-25. |The side brackets extenddownwardly and carry wheels or rollers 26 which are adapted to engage airail 27 which isattached to the hase i1 of the typewriter at the rear.rlhe s 21 are arranged to provide bear- 29-3tL-31, two of which areformed in one fr? the bars and 'two in the other u relation.

in u e respective hearings are s of which 32 is scale in Fig. r1Theseach provided is adapted to'enter the bearings 28 for example, in thesidebar 21 and is held in place by. a latch 38 pivoted at 39 on the side barand adapted to be swung over the extension as clearly shown in Figs. 4and 5.

The end of the spindleis preferably provided with an enlargement orflange v40 so that the spindle is held in position longitudinally`by thepinion 36 and the iange 40,-

Vthe clamping bar in engagement with the outer surface of the spindle.

The arrangement ofi parts is such that the carbon web may be readilyslipped under the clamping bar and held in place by this means as shownin Fig. 5. The spindle is then turned to-wrap the carbon -web upon thespindle allv of the webs being arranged to lead olf either at the top orat the bottom 21 of the frame 20.

when the spindles are mounted in place in the frame 20. For convenienceit will lbe first assumed that they are led ofat the top as shown in.Fig. 4.

An actuating frame 50 which is preferably rectangular in form as shownin Fig. 4, has rack teeth formed at 51 on the bottom edge of its sidebars which are adaptedto rest upon and mesh with-the pinions 36 of thespindles. The side bars are furthermore preferably' graduated as shownin Fig. 1 at.

52, and when the carriage is in position it 1s adapted to bemoved forthand back to vconcurrently actuate the spindles as hereinafter explained.It is held in place by guide rollers 53 which are mounted on brackets 54pivoted at 55 on the side bars The arrangement of parts is such that thebrackets may be swung outwardly on their pivots and the rollersdisengaged from the actuating frame, permitting vit to be lifted olf ofthe pinions. However, when they are in the positions shown in Figs. 1and 4, they do not interfere with 'the movement of the actuating.4

frame forth and back on the pinionsrbutv prevent it from beingoverbalanced or becoming` disengaged from the pinions during theoperation of the'machine.

dotatively mounted on a stud or projection adjacent tothe platen 13, isa gear wheel 61 which meshes gear 62 on the spindle 14 of the platen. A.

ladapted to receive a be secured in pinions 36, the latches 38 with acoperating The gear wheel 61 has a plurality of cirarranged holes 64which are pin or peg shown at cumferentially 65 in Fig. 4.

Mounted on the spindle 14 adjacent to one of the bearings 15 is aratchet wheel 66 with which ,coperates a pawl 67. This pawl 67 ispivoted at 68 and is held in engagement with the teeth of the ratchetwheel byl a spring 69. I t may be released either manually orautomatically, as hereinafter explained, by'means of a key 70, whichspivoted at 71 and has a projection 72 ex tending into the path ofmovementof the pin 65. The arrangement of parts is such that when thepin engages the projection 72 it actuates the key and releases'the pawl67 permitting the platen 13 to be returned to its initial position bythe action of the spiral spring 63 which is associated with the gearwheel 61.

The actuating frame 50 is arranged to a predetermined position by somesuitable latch suc'l as the latch 73- which is adapted to engage the tierod 24 or a locking pin 74 which is adapted to engage the teeth of` therack 51.

The operation of the machine will be understood from the followingdescription.

In utilizing the machine the guide rollers, 53 are first swung back ontheir pivots .55 andthe actuating frame 50 lifted from the arel nextswung outwardly on their pivots 39 and the spins dles 32-3334-35removed. A suitable web 78 having a plurality of superposed layersformed by folding, as shown in Fig. 8, is drawn from a suitable supplyroll (not shown) at the back of the machine upwardly, as shown in brokenlines at Fig. 1, over the tie rods 24 and 25 and under the platen 13,around which it is wrapped' as shown -1n Fig. 2. The paper is heldagainst the platen by the usual means (not shown)and in position forwriting. i When the web is lfirst started inthe machine' it is fedthrough until the line of divisionv between the first and second billsor other forms vwhich may `be `printed on the' web falls substantially'opposite the tie rod 25 at a point designated 80 in Fig. 2. The carbonsheets 41-42-43-44, which are of suitable length and are attached to therespective spindles 32-33-34-35 as al ready explained, are rolled up onthe spindles.

rlihe spindles are next set into the machine with the extensions 37engaging the several bearings 28-29-30-31, their unattached ends beingintroduced from opposite sides between the folds of the web 7 S. As eachspindle is introduced beginning, for example, lwith the spindle35, whichis introduced between the bottom layer and the layer next above it, itscarbon sheet is drawn out from the roll between the folds until itextends to the p'oint 80.

The. Spindle 34 is next introduced and its carbon sheet 43 spread outbetween the second and third folds from the bottom. ln like manner thespindles 33 and 32 are introduced and their carbon sheets 42 and 41spread between the upper layers. The spinj dles are secured in positionby swinging the latches 38 back into place as soon as they are set inthe machine and ,the actuating frame 50 is next mounted on the pinions36 with its teeth 51 meshing therewith. The

frame is held in place by the guide rolleIS- 53 which are next swunginto position.

lt is evident that on the one hand, any movement of the actuating framewill pro duce a concurrent rotation of the spindles 32-33-34-35, and onthe other hand, a movement of the web which unwinds the carbon sheets,will turn the spindles and produce a movement of the actuating frame.This is what happens when the web is now fed forward by turning thevplaten 13 in the usual manner.

When the platen is turned so that the second bill or form on the web isin the machine, it is evident that the first bill which has no carbonorV other duplicating sheets, has now passed through the machine but hasnot been written on. The second bill is now in position to be made outin the usual manner and as it is written out the copies will be producedon account of the interposed "carmn' sheets.

The pin 65 is set in one of the holes 64, depending on the length of thebill, in such position that when the bill is completed the pin willengage the projection 72, actuate the key 70, and release the pawl 67,thereby permitting the platen to be returned to the position which itoccupied at the beginning of the bill, by the spring 63.

The latch 67 is released and the'gear 63 uncoupledffrom the platen bymeans of the clutch pin while the web is, being adjusted into positionto start the bill. Any other suitable means for .releasing the platenfrom the spring 63 until thev web has been adjusted to this point, maybe employed.

Assuming that the bill has been written, the key 7 0 actuated and theplaten returned to its initial position by the spring, the operatorpushes back on the actuating frame 50, thereby turning the spindles 32,33, 34, 35 Vand winding up the carbon paper as the web moves backwardly.The carbon sheets and the web have now returned tothe posi tion in whichthe carbon sheets extend, to the point 8O in 2, this being permissiblewithout pulling the web out of the machina' by the first blank billwhich is still attached to the web although the second one is alreadylilled out.

The actuating frame 50 is next locked or latched in position either bythe latch 73 which is adapted to engage the rod 24, if thebills are of apredetermined standard length for which the machine is designed, or bymeans of a pin 74 which is arranged to engage the teeth of the rack onthe actuating frame and hold it in any position which it may beadjusted. lThe platen is next actuated in the usualmanner to draw theweb forward and since the actuating frame is locked so that the carbonsheets cannot be unrolled the web advances without the carbon sheets.This is continued for the length of one bill', thereby transferring theweb relative to the carbon sheets and preparing it for the next bill.

As the web is now advanced the first blank bill may be torn 0H' bydrawing it into engagement with the cutter 19. rlhe web then still'further advanced until the end of the second bill is substantially atthe point 80; then .the actuating frame 50 is released and the webadvanced togetherwith the carbon sheets until the third bill is ready tobe written upon. When the. third billv is completed the process ofbackingvthe web, holding the carbon rolls against rotation, drawing theweb forward relative to the carbon sheets, etc., is repeated. Thus thecarbon paper is not cut o' or lost and may be used repeatedly until itis worn out.

It is of couse immaterial whether the actuating frame moves'backward orforward Ywhen the web advances and this will depend -direction if thecarbon sheets are led off from thel bottom of the spindles. ln thelatter case the latch 7 3 will be located at the opposite end of theactuating frame in positon to engage the rod 25 instead of the ro 24. 1
